ALANSON GARY, OF NEW YORK, N. Y., ASSIGNOB TO AMERICAN FENCING COMPANY,OF SAME PLACE.

MA CHlNE FOR MANUFACTURING METALLIC BARBED RIBBON FOR FENCE-WIRE.

SPECIFICATION forming part of Letters Patent No. 226,034, dated March30, 1880.

Application filed November 6, 1879.

To all whom it may concern Be it known that I, ALANSON CARY, of thecity, county, and State of New York, have invented a new and usefulImprovement in Machines for Manufacturing Metallic Barbed Ribbon forFence-Wire, of which the following is a specification.

The object of my invention is to construct a machine for manufacturingmetallic barbed 1o ribbon for the wire used for fences so as to give tosuch wire a barbed edge; and the invention consists in a machinecombining areciprocating head carrying the cutters, a feedbed, anddieplate, feeding-rollers, and an intermittent feed motion, whereby theribbon is fed forward beneath the cutters and the operation performedrapidly without waste of material.

The construction and operation will be more particularly described withreference to the accompanying drawings, wherein Figure 1 is a frontelevation of the machine. Fig. -2 is a rear elevation. Fig. 3 is a planview. Fig. 4 is a sectional side elevation on line 00 00 of Fig.

3. Fig. 5 is a plan view of the feed-bed and die-plate. Fig. 6 shows apiece of the ribbon after passing through the machine. Figs. 7 and 8 aredetail views.

Similar letters of reference indicate corre- 0 sponding parts.

A is the bed-plate of the machine, upon which is fixed the pillow-blocka, that supports the feed-bed B, and is extended up and formed as a box,a, for the horizontal driv- 3 5 ing-shaft b, that is fitted with apulley, I), for

connection of the power by belt.

Upon the forward part of the box a, above the bed B, is fixed a head, 0,that carries in a dovetail recess the slide 0, that is connected,

through the head 0, to the shaft 1) by a crankpin or cam, so that theslide 0 is vertically reciprocated by the revolution of shaft 1).

Upon the bed-plate A, at opposite sides of the pillow-block a, are fixedthe standards d 5 d and e e, which carry, respectively, the shafts f fand g g of the upper and lower feed-rollers, h h and i it, thesefeed-shafts of each pair of rollers being parallel with thedriving-shaft b and the feed-rollers at opposite sides of the bed B.

The shafts ff of the feed-rollers h h are at the delivery side of thebed B. The upper shaft, f, is sustained by the forward standard,

(I, in a box,f that is fitted to slide in a vertical slot in thestandard, and is pressed down 5 5 by a spiral or other spring, If, so asto impart pressure to the feed'rollers. The upper shaft,

9, is sustained in the standard 6 by a sliding box, 0', in the samemanner, except that instead of a spring there is a rod, 70, littedin thestandard 0, to rest on the box 0, and upon the head 0 is hung ahand-lever, l, resting on rod 70, by which pressure may be given to thefeedroller 0', for purposes hereinafter described.

The lower feed-rollers, h '5, are formed each with a peripheral groove,as shown, of the width of the ribbon that is to be operated upon, andthe upper rollers, h i, are formed of a width to enter the said grooves.v

The intermittent feed motion is given dur- 7o ing the upward movement ofthe slide 0 by mechanism at the back of the machine. (Shown in Figs. 2,3, and 4, and next described.)

Upon the rear ends of the lower feed-shafts,

f g, are fixed gear-wheels m m, respectively, which are connected by anintermediate pin; ion, n, that is fitted to revolve freely on a studprojecting from the block a. Upon either shaft, preferably f, is fixed aratchet-wheel, 0, and the same shaft carries loosely an arm, 1), uponthe outer end of which is a pawl, q, that is kept in contact with awheel, 0, by a spring,

19 This device constitutes a pawLcarrier that is operated by the rod 4,which is connected to arm 1) and to a cranlcpin on the drivingpulley b,so that the feed-shaftsf g are given an intermittent revolution in thesame direction at once. The shafts f g are geared to shafts f gby thegearing s s and t t, as shown, and the rod r may be fitted adjustably atits 0 connection to pulley b or arm 19, so that the amount of feed ateach movement may beregulated.

In the lower end of the reciprocating slide care fixed the cutters 0rpunches it. These 5 are preferably three in number, and will be fittedadjustably in any desired manner, so that they may be set down tocompensatefor wear.

In Fig. 7 the manner of fitting the punches 10o is shown, wherein theyare clamped in a recess of the slide 0 by a plate, a, with blocksintervening to retain them the proper distance apart, and are presseddown by screws n fitted in slide 0. The cutters u are each formed with acutting-edge inclined at an angle of about forty-five degrees to thedirection of the feed, so as to cut or nick the ribbon, as shown by Fig.6, about half its width, more or less.

The feed-bed B is recessed to receive the fixed cutters 22', forming thedie-plate, which cutters are of the sameshape as cutters u, andareclamped by a block that. is to be set up and held by screws 11. (Shownin Fig. 8.) Upon the bed-plate B are adjustable plates 10, held byscrews, between the edges of which plates the ribbon passes over thecutters c.

In operation the metallic ribbon is entered between the rollers 2' iacross the bed B to the rollers h h, and during its passage is cut bythe reciprocating cutters a. The feed takes place while the cutters uarerising, and each movement of the feed should carry the last out portiona suitable distance beyond the cutters. The action of the cutters tendsto bend the cut portion down, which assists the cutting, but the ribbonis bent flat again by the feed-rollers h 71/, so that it may be readilyrolled for further manufacture.

In first feeding the ribbon as described, the end is to be insertedbetween the rollers i t",

and the requisite pressure given by the lever l to carry the ribbonforward until caught by the rollers h h. The lever l is then to berelieved, so that the feed will be accomplished by the last -namedrollers only. By these means the ribbon may be cut at its extreme end,and there will be no waste of material at its first entering. Byrelieving the entering rollers or pressure, as mentioned, there will beno risk of buckling or strain by reason of inequalities of feed in thetwo sets of rollers.

The product of this machine is used in the manufacture of barbedfence-wire by winding around a core, as shown in my patent granted July15, 1879.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent Y The combination, in a machine formanufacturing metallic barbed ribbon for fence-wire, with thereciprocating and fixed cutters, the feed'bed, and the intermittentfeed-rolls, of the entering feed-rolls, fitted with a device forimparting the required pressure and having an intermittent revolution,as and for the purpose specified.
